从免疫状态的角度探讨CD8+CIM5RA+CD28一T细胞亚群(简称CD28+T细胞)和第二信号共刺激分子CD8+CD28+(简称CD28+),CD8+CD152+(简称CD152+)的表达变化.根据慢性乙型肝炎防治指南,选取不同免疫状态的慢性HBV携带者,HBeAg阳性慢性乙肝患者,HBeAg阴性慢性乙肝患者各40例.对照组40例:自述无肝炎史,肝功能正常;HBsAg,anti....
In healthy carriers of human cytomegalovirus (HCMV), the virus-specific memory CD8+ T-cell population is often dominated by CD28− CD45RAhi cells that exhibit direct ex vivo cytotoxicity but whose capacity for proliferation and generation of further memory cells has been questioned. We show ...
CD45RA+CD27−CD28− T cells within both the CD4 and CD8 compartments also exhibit an increase in DNA damage visualized by phosphorylated H2AX (γH2AX), a member of the histone H2A family that is phosphorylated in response to double-strand breaks [23•]. In addition, highly ...
We classified the peripheral blood CD4+ T cells from healthy subjects and RA patients into the six subsets by four cell-surface markers, CD45RA, CCR7, CD27, and CD28. Flow cytometry analysis revealed six major populations of human CD4+ T cells (Fig. 1A). The CCR7 + CD45RA–CD27–CD28...

Circulating T cells in patients with untreated acute myelogenous leukemia are heterogeneous and can be activated through the CD3/TCR complex The majority of CD4+ and CD8+T cells were CD45RA+ cells. The T cells could be stimulated to release IFN in response to anti-CD3 plus anti-CD28 ... ...
